Simple, secure, scalable external collaboration in Microsoft 365

Extranet User Manager (EUM) lets your business connect and collaborate with external clients, partners, vendors, and board members, while IT keeps full control of security and governance. Onboard guests in minutes, share documents safely, and give external users a clean, fully branded experience, without the insecure workarounds of ad hoc sharing.

Business teams manage their own external users within the guardrails IT sets, so work gets done independently and nothing leaves your Microsoft 365 tenant.
